CABINET FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 675,283, dated May 28,1901.

Application filed August 20, 1898. Serial No. 689,142. (No model.)

To aZZ whom it may concern:

Be it known that we, THEODOR KUNDTZ and ANDREW EIBEN, of Cleveland,county of Guyahoga, and State of Ohio, have invented certain new anduseful Improvements in Cabinets for Sewing-Machines, 850.; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use the same.

Our invention relates to improvements in tables or cabinets forsewing-machines, &c.

This invention pertains more especially to mechanism for actuating andsupporting the tilting leaf that carries the sewing-machine head orother machine; and the invention consists in certain features ofconstruction and combinations and arrangements of parts hereinafterdescribed, and pointed out in the claim, and constituting an improvementof the subject-matter disclosed in United States Letters Patent No.607,862, granted July 26, 1898.

In the accompanying drawings, Figure I is a front side elevation of theupper portion of a table or cabinet embodying our invention, and in thisfigure portions are broken away and in section to more clearly show theconstruction. Fig. II is a top plan. Fig. III is an end elevation,mostly in vertical section on line III III, Fig. I. Fig. IV correspondswith Fig. III, except that in this figure the load-carrying leaf is inits downwardly-tilted position and the mechanism instrumental in theelevation or actuation of the said leaf is in a corresponding position.Fig. V is a front side elevation of the slide D and connected parts inthe slides lower position. Fig. VI is an enlarged section on line VI VI,Fig. II. Fig. VII is a section on line VII VII, Fig. VI. Referring tothe drawings, A designates the top of the table or cabinet. Top A isprovided centrally with a rectangular opening a, that extends throughthe top. A verticallytilting leaf B is arranged to enter and occupy thesaid opening and is horizontally hinged or pivoted at its forward end atB to and longitudinally of top A at the forward end 0 opening a. MemberB is known as the 1oadbearing leaf, that carries the sewing-111achinehead or other machine (not shown) of the table or cabinet. When themachine is not in use,leaf B is tilted downwardly below top A, as shownin Fig. IV, and the said leaf is again tilted upwardly or elevated intoopening a when the machine is required for use. The said leaf B isoperatively connected with the lifting leaf 0, that is horizontallyhinged at one end, as at O, to and transversely of the left-hand end oftop A, and the arrangement of parts is such that when said leaf 0 is ina horizontal position and forms a leftward extension of top A leaf B isin its upwardlytilted or elevated position, and when leaf 0 closesopening CL and rests upon top A leaf B is in its downwardly-tiltedposition, and the said leaf B is elevated or lowered according as thelifting leaf 0 is tilted to the leftor right.

The improved mechanism employed in establishing operative connectionbetween leaf B and leaf 0 comprises, preferably, the following: Thecabinet or table at the rear is provided with a back A, that at itsinner or forward side and at or near the left-hand end is provided witha vertical or upright slideway formed, preferably, by two verticalmetallic bars (1/,- arranged a suitable distance apart and removablysecured by means of screws 0. to the inner or forward side of the back.A metallic slide D engages and is adapted to reciprocate endwise of (upand down) the said slideway. Slide D at its lefthand edge is providedwith a forwardly-projecting arm (1, that extends in under andtransversely of the left-hand portion of the load-carrying leaf B. SlideD is provided at the top with an upright link (1 that has its lower endpivoted, as at (1 to the slide horizontally and transversely of thecabinet. The upper end of link (1 is pivoted, as at 01 horizontally andtransversely of the cabinet to an inwardly-projecting short arm G2formed upon one end of the rod or lever G, that has its opposite endpivoted horizontally to and transversely of leaf 0, as at G. Lever orrod G constitutes the slide-lifting device and during its operationslidably works upon a fulcrum formed by a horizontally-arranged pin orrounded member g, that is supported from and within the top A above andat the left of the path of slide D. Top A is slotted or cut away, as atA Fig. II, to accommodate the location and operation of the said rod orlever G and the operative connection between the said member G and theslide. The load-carrying leaf B is provided upon the under side of itsleft-hand end, at or near its rear edge, with a roller B that rests uponarm d, and it is obvious that the said leaf is lowered or tiltedupwardly according as the slide D and its lifting-arm d are lowered orelevated. In.Figs. I and III the said slide is shown in its upperposition, and in Figs. IV and V the slide is shown in its lowerposition. The arrangement of the operative connection between the saidslide and leaf 0 is such that the slide and its arm (land the engagingload-carryingleaf are in their elevated positions when the said leaf 0is in its open position, wherein it forms,as already indicated,anextension of the top of the table or cabinet, and the said slide andload-carrying leaf lower by gravity when the lifting leaf is tilted fromits open position to the right and over the opening in the aforesaidtop. The trend of the lifting lever G is such that the lever willperform its function efficiently and easily. The slide-arm d, at theforward side of and near the slide, is provided with an upwardly andrearwardly extending incline cl", that has the arrangement required torenderit capable of lifting roller I3 and the connected leaf B intotheir extreme upper position, and the said arm, at the rear of the saidincline, is provided with a rest (1 upon which the roller, andconsequently the lifting leaf, have hearing when the said leaf is in itsupwardly-tilted position.

Leaf B, when the same is in its upwardlytilted position, does notentirely close the rear portion of the opening a in the top of the tableor cabinet, and the said rear portion of the said opening isclosed by asupplementary leaf 1), that is arranged to enter and occupy the rearportion of the said opening at the rear of leaf B and is horizontallyhinged or pivoted at its ends, as at l), to and longitudinally of top A.During the lowering of leaf Bthe supplementaryleaf tilts downwardly bygravity, as shown in Fig. IV, and the rear end of slide-arm (Z, rearwardof the rest (1, is enlarged upwardly, as at (i that has the arrangementrequired to render it capable during the elevation of the slide toengage the aforesaid supplementary leaf and tilt the said leaf upwardlyinto the leafs horizontal position, wherein the said leaf, as alreadyindicated, closes the rear portion of the aforesaid opening a. Theslide-arms portion d, to facilitate its operation of lifting leaf b, hasa rearwardly and upwardly extending incline d arranged to engage theleaf when the latter is in its depending position at the junction of theforward edge and under side of the leaf. The said leaf 1) is cut away onits under side, as at N, to accommodate the location of the incline d ofthe slide-arms portion (Z when the slide is in its elevated position.

The load-carrying leaf B has its rear and free end rabbeted upon itsunder side, as at B and leaf Z) has its forward or free end rabbetedupon its upper side, as at b and the rabbeted end of leaf l3 rests uponthe rabbeted end of leaf 1) in the upwardly-tilted position of the saidleaves, and consequently the arrangement of parts is such as toaccommodate the rabbeted construction of the aforesaid leaves. The leafB and the supplementary leaf 1) are thus adequately supported at theirleft-hand ends in their elevated position. The right-hand ends of thesaid leaves should also be adequately supported. The support for theright-hand ends of leaves B and 1) comprises, preferably, a slidingshelf that is rigidly form ed upon a horizontally-arranged andhorizontally-swinging bar K, that extends forwardly and rearwardly ofand within the right-hand end of the cabinets top and is pivotedvertically, as at K to the top. In its normal and inoperative positionbar K has its shelf-forming end within the cabinet-top and in itsoperative position has the said end extending in under the right-handends of the leaves B and b. A suitably-applied spring K acts to retainbar K in the latters normal or inoperative position and engages theouter side of a lug or flange K, formed upon and depending from the rearend of bar K. The means for actuating bar K from the latters inoperativeinto an operative position comprises, preferably, alongitudinally-sliding bar 0, that is arranged horizontally andlongitudinally of the cabinet and engages a correspondingly-arrangedgroove or slideway 0, formed at the upper end of back A. Bar 0 isarranged to be engaged at its left-hand end during the actuation of theload-carrying leaf from the latters downwardly-tilted position into itselevated position by a roller (Z that is mounted upon a pin d", thatforms-the pivotal connection between link d and the lifting-lever G,between the lever and the link, and bar 0 has its right-hand endarranged to engage the inner side of lug or flange K of bar K during thesaid actuation of the said leaf. The arrangement of parts is such,therefore, that when the load-carrying leaf in tilting the latterupwardly has been actuated into its elevated and horizontal positionroller 61 shall have actuated bar 0 to the right and bar 0 shall in turnhave shifted bar K into the latters operative position against theaction of the spring K that acts also to retain the said bar 0 in itsnormal or inoperative position.

Ourimproved mechanism for actuating and supporting the load-carryingleaf is meritorious in that itis simple, convenient, and out of the way.

The cabinet-top is of course suitably recessed to accommodate thelocation and op' eration of bar K.

The lifting end of bar K is beveled, as at K, as shown very clearly inFig. VII, and engages the undercut or beveled portion of the undercutmetallic plate If, that is secured to the under side of leaf 1). Thebevel on the shelf causes the latter to lift the leaf b, andconsequently the leaf B, into an exactly horizontal position when thesaid leaves have been tilted upwardly by the lifting mechanism connectedwith the leaf 0. The plate I) prevents wearing away of the leaf 1), thatis made of wood, by the bar K.

What we claim is In a table or cabinet of the character indicated, thecombination, with the top having an opening therethrough, and theverticallytilting load-carrying leaf hinged or pivoted to the top, of amovable shelf-forming device arranged to be moved into the positionrequired to afiord a support for the said leaf, a suitably-supportedsliding bar arranged to ac- THEODOR KUNDTZ.
